Dundee's Ryan Conroy scored his team's winner
Dundee recovered from being a goal down after five minutes to win this middle-of-the-table match at Cappielow.
Morton's Andy Jackson scrambled the ball over the line for the opener after five minutes.
The home side had a strong penalty claim turned down and almost immediately Gavin Rae equalised with a shot with the outside of his boot.
In 56 minutes Jake Hyde cut the ball back for Ryan Conroy whose volley flew past Morton goalkeeper Dominic Cervi.
